DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVE
Revision: June 20062007 Versa
DTC P0740 TORQUE CONVERTER CLUTCH SOLENOID VALVEPFP:31940
DescriptionUCS005O T

The torque converter clutch solenoid valve is activated, with the gear in D4 and D3 , by the TCM in
response to signals sent from the vehicle speed sensor and the ECM (throttle opening). Lock-up piston
operation will then be controlled.

Lock-up operation, however, is prohibited when A/T fluid temperature is too low.

When the accelerator pedal is depressed (less than 2/8) on lock-up condition, the engine speed should
not change abruptly. If there is an abrupt change in engine speed, there is no lock-up.
CONSULT-II Reference ValueUCS005OU
Remarks: Specification data are reference values.
On Board Diagnosis LogicUCS005OV

This is an OBD-II self-diagnostic item.

Diagnostic trouble code “P0740 T/C CLUTCH SOL/V” with CONSULT-II or 7th judgement flicker without
CONSULT-II is detected when TCM detects an improper voltage drop while it tries to operate solenoid
valve.
